The brake system needed to reduce and
stop the speed of the car usually uses
the friction to reduce the speed. In order
to have a safe friction constant which
plays a great role in breaking system,
the steel friction material is being used.
Also, in order to improve its durability
to heat, the vent type disc which has
the vent for the air is being used.
Also, in order to minimize the JUDDER
effect during breaking, a careful choice
of material is required. Also, since this
product needs high precision technique,
it must by assembled by installing it
to the HUB.
